T0 If/ZZ wir/0771, t may concern:

Be it known that I. WILLIAM I. McCAUs- LAND, a citizen of the United States, residing at I/Vheeling, in the county of Ohio and State of I/Vest Virginia, have invented certain new and useful Improvements in Dish-flashing Machines, of which the following is a specification.

This invention relates to improvements in dish-washing machines of the type embodying an outer receptacle for the washing duid, an inner stationary dish-receptacle disposed in the outer receptacle in spaced relation thereto, and a water-wheel located in the space between the aforesaid receptacles and adapted to force the washing fiuidinto the dish-receptacle, so as to thoroughly drench. and cleanse the dishes or utensils therein.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

IVhile certain features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure lis a vertical sectional view through the dish-washing machine. Fig. 2 is a hori- Zontal sectional view taken on the line X X of Fig. l looking' down into the dish-receptacle. Fig. 3 is a horizontal sectional View on the line Y Y of Fig. I looking downwardly. Fig. 4 is a detail perspective view of the waterwheel.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In carrying out the invention I provide a casing or support 4, in which partis disposed the dish-washing receptacles and operating mechanism comprising the invention. The sides of the casing 4 are secured to the metal frame 5, disposed at the outer extremity of said section, said frame being horizontally arranged and of skeleton form, as shown most clearly in Fig. 2 of the drawings. The frame is preferably made in sections suitably at-A tached by clamping-bolts, such as shown at 6, and projected from the under side of the frame 5 at the corner portions thereof are angle-lugs 7, the sides of the section 4 being attached to said lugs by means of screws or suitable fastenings. The frame o is formed centrally thereof in the form of a ring, and a receptacle 9 is supported by said ring, said receptacle 9 being provided at its upper portion with an annular flange IOOVerlapping the ring 8 of the frame 5, thereby rigidly holding the receptacle from any movement at its upper portion. The outer receptacle 9 has disposed therein an inner perforated receptacle 1l, the latter being designed to directly receive and support the dishes in the washing operation. The dish-receptacle 11 is joined by solder or otherwise attached to the receptacle 9, and the sides of the receptacle ll are provided with lines of perforations through which the water or washing fluid passes when caused to drench the dishes or utensils which may be disposed within the receptacle l1. The bottom of the receptacle l1 is provided with an aperture, and a perforated bottom plate 12 is disposed over the 'aperture aforesaid, resting upon the portions of the bottom of the receptacle ll adjacent the peripheral portion of the aperture therein. The bottom plate 12 is spaced some distance from the bottom of the outer receptacle 9, thereby forming a water-chamber 13 in the lower portion of said receptacle 9, a water-wheel 14 being disposed in the water-chamber I3 and operable so as to force the water through said chamber upward through the perforations in the sides of the dish-receptacle 1l, so as to thoroughly drench the dishes in the washing operation. The water-Wheel 14 comprises a flat body of circular formation from which inoline upwardly a plurality of blad es or flights 15, the latter operating adjacent the sides of the outer receptacle. The sides of the inner receptacle 11 are spaced from those of the outer receptacle 9, and the position of the blades or flights 15 of the water-wheel is such that when this wheel is forcibly revolved the washing iiuid in the water-chamber 13 will be copiously fed through the perforations in the sides of the receptacle ll, as above described. It is designed that the capacity of the waterchamber 13 will be such that same will receive the entire body of the washing fluid, usually scalding water, so that this fluid will not stand in the bottom of the receptacle ll, but will constantly and quickly drain through the bottom plate l2 after having been fed into the receptacle l1 through the perforations in the sides thereof. The arrangement of the receptacles 9 and ll, whereby the water-cham- IOO ber 13 is formed, is extremely advantageous, in that no part of the water fed to the receptaele 11 will remain in the receptacle for any determinate period of time, and thus cause th`e formation of a sediment-line upon the dishes therein when the revolution of the water-wheel is stopped. The means for operating the water-wheel consists, preferably, of a vertical shaft 16, -which passes through an opening disposed centrally of the bottom of the receptacle 9, said shaft being' suitably keyed to the water-wheel at its upper end. rlhe shaft 16 passes through a tubular bearing 17, extended through the opening in the bottom of the receptacle 9, said bearing 17 consisting of a tube flanged at its upper end. as shown at 18, and threaded in the length thereof. A jam-nut 19 screws upon the bearing member 17, and a packing-nut 20 is likewise carried by the part 17 in order to provide a water-tight joint and prevent the passage of any of the water from the receptacle 9 through the part 17 aforesaid.

The means for actuating the shaft 16 is manually or otherwise operated, a crank-shaft 22 being mounted in a gear-frame 23, disposed beneath the receptacle 9, and this shaft 22 is provid ed with a beveled gear 24, meshing with a similar gear 25, suitably mounted in the gearframe 23. A spur-gear 26, operated by the gear 25, meshes with a spur-gear 27, keyed to the lower portion of the shaft 16, so that when the handle 28 is operated motion will be transmitted to the shaft 16 and the waterwheel thereby revolved. The gear-frame 23 may be supported upon a shelf 2l or similar part.

In the provision of a water-chamber 13 it will be noted that the weight of the water in said chamber gives rise to pressure against the blades or iiights 15 of the wheel 14, and an essential feat-ure of the invention is comprised in the means for relieving the parts '15 of the pressure of the washing iuid so as to facilitate the operation of the machine and enable the water-wheel to be revolved by a minimum amount of power. For the above purpose an annular partition 29 is disposed in the chamber 13 adjacent the inner edge portions of the blades or [lights 15, said partition being in the form of a ring, approximately, the sides of which diverge toward the upper edge portions thereof, so as to conform somewhat with the formation of the sides of the outer receptacle 18. The partition 29 is provided with an annular flange 30, resting upon the bottom of the receptacle 11 and overlapping the apertured bottom thereof, said receptacle 11 thus holding the partition pendent therefrom in such a position that same is interposed -between the body of the Water within the chamber 13 and the blades of the wheel 14. rlhe water or washingfluid of course passes freely beneath the partition 29, so as to be received and deflected upwardly by the blades 15 as the Wheel 14 is revolved. However, it is clearly apparent that the weight ofthe Water not beingdirectly against the blades relieves the water-wheel to such an extent as to make the same operable with much less power than would otherwise be necessary. In orderto prevent the body of the water in the chamber 13 from swirling, due to the rotation of said wheel when the machine is in operation, diverging partitions 31 project from a point central of the partition 29, said partitions 31 being connected at their innerends and having their outer ends resting upon or against the inner sides of the partition 29. rlhe partitions 31 may be of any suitable formation, any suitable number of the same may be utilized and, further, if desired, these partitions may be secured permanently to the partition 29 and made a part thereof. The function of the partitions 31 is to prevent the swirling motion of the water in the chamber 13, since this motion prevents the free flowing of the same beneath the partitions, detracting from the efficiency of the device in general, and said partitions 31 are disposed across the partition 29 from side to side in accomplishing the purpose for which they are provided.

A suitable cover-plate 33 is disposed so as to rest upon the upper portion of the casing 4, this-plate being' of substantially rectangular form and having edge portions overlapping the sides of the casing. The plate 33 has a circular opening substantially the same size as the receptacle 9, so that the dishes or utensils to be washed may be readily disposed in the receptacle 11.

Having thus described the invention, what is claimed as new is- 1. In a dish-washing machine, the combination of an outer receptacle, aperforated receptacle disposed within the outer receptacle and spaced therefrom so as to form a waterchamber in the lower portions of said outer receptacle, a waterwheel disposed in the water-chamber aforesaid, blades or iiights projected upwardly from4 the water-wheel ad- IOO IIO

jacent the sides of the outer receptacle, an

annular partition adjacent said blades or flights and adapted to separate the same from the body of the Vater in the water-chamber, and other partitions between the sides of the annular partition.

2. In' a dish-washing machine, the combination of an outer receptacle, an inner receptacle spaced from the outer receptacle and having its sides perforated and its bottom apertured, a perforated bottom plate over the aperture in the bottom of the inner receptaole, the bottom of the inner receptacle being spaced from that of the outer receptacle,

forming a water-chamber, a water-wheel disposed in the water-chamber aforesaid, upwardly-inclined ights or blades projected from the water-wheel and operating adjacent the sides of the outer receptacle, an annular partition adjacent the inner edge portions of the blades or flights, an annular flange projected from the upper portion of said partition and overlapping the bottom portion of the inner receptacle, and other partitions be- I0 tween the sides of the annular partition and supported thereby.

In testimony whereof I aiX my signature in presence of two witnesses.
